GEORGE M. EATON, OF PITTSBURGH, PENNSYLVANIA, ASSIGNOR TO WESTINGHOUSE ELECTRIC AND MANUFACTURING COMPANY, A CORPORATION OF PENNSYLVANIA.

LUBRICATING DEVICE.

Specification of Letters Patent.

Patented May 21, 1918.

Application filed October 27, 1915., Serial No. 58,167.

To all whom it may concern Be it known that I, Gnonon M. EATON, a citizen of the United States, and a resident of Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented anew and useful Improvement in Lubricating Devices, of which the following is a specification.

My invention relates to lubricating devices, and it refers specifically to the oil and waste lubrication of bearing housings for dynamo electric machines. 1

One object of my invention is to provide a lubricating device having communicating oil and waste chambers which have separate and independent openings and covers to permit of the supply of oil to the waste through the oil filling chamber without exposing the waste to dirt.

Another object of my invention is to provide a passageway for measuring the level of the oil contained in the waste chamber. This passageway will hereinafter be referred to as a sounding pipe.

In lubricating devices used at the present time, the oil and waste openings are provided with a single cover, making it necessary to expose the waste and eventually the bearing to dirt whenever inspection is made to determine the quantity of oil in the housing or when oil is supplied to the waste, but, by the use of my present invention, the waste chamber need be opened only when the waste is renewed.

My invention is illustrated in the accompanying drawing in which Figure 1 is a view, partially in section and partially in end elevation, of a split-frame railway motor constructed in accordance with my invention, and Fig. 2 is a detail view, showing the covers for the oiling and sounding pipe and the waste chamber shown in Fig. 1.

Referring to the drawing, a split-frame railway motor 1 is provided with an armature bearing housing 2 which embodies a waste chamber 3 and bearing member 4. The waste chamber has an opening 5 that is provided with a cover 6, an opening 8 through which an oiling and sounding pipe 7 projects, and a lug 9 to aline the pipe 7 with the opening 8.

It is preferred to have the pipe 7 welded to the housing 2, although such a structure is not necessary, as the pipe may be attached to the housing in any Well-known manner and, if desired, may be made an integral part of the housing *2. The lower end of the pipe '7 within the waste chamber 3 is cut diagonally to insure against stoppage of the pipe when it rests on the bottom of the chamher 3. The pipe 7 should be sufficiently large to admit a measuring stick or other means for determining the level of the oil in the waste chamber.

The bearing member a is provided with an opening 14: for permitting the waste within the waste chamber 3 to have contact with an armature shaft 12.

The opening 5 is used for supplying waste to the chamber 3, and when waste has once been supplied, the waste chamber need not be opened except for renewing the waste. W'hencver it is necessary to oil the waste, a cap 10, or other suitable cover, is removed and the oil supplied through the pipe 7.

Various modifications in the structu'al details of the lubricating device may be effected without departing from the sprit and scope of my invention, and I desire, therefore, that only such limitations shall be imposed as are indicated in the appended claims.

I claim as my invention:

1. In a lubricating device, the combination with a housing having a tube adapted to receive an oil-level measuring device, a waste-containing chamber, and a separate cover for each, of a bearing member associated with said housing and disposed adjacent to said waste-containing chamber.

2. In a lubricating device, the combination with a member having a chamber containing waste and an op'enmg therefor, of a cover for the opening, an oiling pipe extending into the waste chamber and a removable cap fitting the inlet end of the pipe, whereby oil may be applied to the waste without removing the chamber cover.

3. In a lubricating device, the combination with a member containing a waste chamber having an opening and a cover therefor, of an oiling and sounding passage extending through the member to a point adjacent the bottom of the chamber, and a separate cover for said passage.

4. In a lubricating device, the combination with a member including a waste chamber provided with two openings, a cover for one opening and a lug within the chamber alined with the second, opening, of an oiling pipe extending through the second opening and held in alinement by said lug.

5. A housing. provided With interconnected oil-filling and waste-c0ntaining chambers respectively having separate and independent openings therefor, said oil-filling chamber being adapted to admit means for determining the level of oil in said Waste-containing chamber.

6. The combination With a bearing housing having a Waste-containing chamber,

of a sounding tube adapted to receive a device for measuring the level of oil in said Waste-containing chamber.

7.-The combination With a bearing housing having a Waste-containing chamber, and a cover for said. chamber, of a tube for ad mitting oil tosaid chamber, and a separate cover for said tube, said tube being adapted to receive a device for measuring the level of oil in said chamber.

8; In a lubricating device, the combination with a Waste chamber, a Waste-removing opening in said chamber, a cover for said opening, an auxillary opening 1n said chambe1',. alug Within said chamber alined With said auxiliary opening, an oil tube extending through. said auxiliary opening and held in alinement by said lug, and a separate cover for said tube.

9. In a lubricating device, the combination With a member having a chamber adapted to contain Waste, said chamber being provided with an opening through which Waste may be introduced and removed, of a cover for said opening, an oiling and sounding passage leading into said Waste chamber, and a removable cap fitting the inlet end of said passage, thearrangement being such that by removing said cap, oil may be supplied tosaid passage and chamber and the depth of oil in the chamber may be determined Without removing the cover of the chamber and exposing the \vastein said chamber to dirt.

In testimony whereof, I have hereunto subscribed my name this th day of Oct. 1 915,

GEORGE M. EATON.
